Abstract
Description
Technical Field
[0001] The utility model relates to the field of grate bars, in particular to split-type heat-insulating and energy-saving grate bars. Background Art
[0002] The grate bar is the main accessory on the sintering machine trolley. The function of the grate bar is to form a trough-shaped space with the trolley guardrail to accommodate and carry the ore. The part of the grate bar that contacts the ore is the upper surface. The two ends of the upper part of the grate bar are subjected to force and play a supporting role. The bottom of the grate bar has two functions. The first is to fix the grate bar when turning over and unloading so that it cannot fall off. The second is to play a supporting role when the top of the grate bar is under pressure, which can effectively prevent the grate bar from bending.
[0003] There are several problems that are prone to occur during the use of existing general grate bars. First, the service life is short and not resistant to high temperatures. The maximum temperature during operation reaches about 1000 degrees. Then, it is not corrosion-resistant. The production process has a high maintenance frequency, which affects production output. Then, the general grate bar has a short service life of about one year or even less, and the production cost is high. Finally, local over-fire occurs during the production process, and the temperature is too high, which can easily cause product deformation or direct and rapid burning. The production of grate bars adopts the traditional casting high-energy consumption process, which has high energy consumption and is not environmentally friendly.
[0004] Therefore, it is necessary to invent split-type heat-insulating energy-saving grate bars to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a split type heat-insulating energy-saving grate bar, which can achieve good high-temperature resistance and corrosion resistance by connecting the surface body, guide ribs, non-working surface body, heat insulation layer, heat insulation protection layer, surface body groove, surface body protrusion block and upper working surface, and increase the overall service life. When the equipment is working, it can reduce the number of shutdowns and maintenance time, increase production, and reduce the work intensity of the staff who replace the grate bars. After the service life is reached, it only needs to replace the upper working surface to continue to use it, reducing the cost of use. Finally, the production process of the split type heat-insulating energy-saving grate bar is simple and does not use high energy consumption. The casting process reduces carbon emissions, improves production efficiency, expands the overall scope of application, and is more convenient to use in work, so as to solve several problems that are easy to occur in the use of general grate bars in the prior art. First, the service life is short and not resistant to high temperatures. The maximum temperature during operation reaches about 1000 degrees. Then, it is not corrosion-resistant, and the maintenance frequency in the production process is high, which affects production output. Then, the general grate bars have a short service life of about one year or even less, and the production cost is high. Finally, local over-fire occurs in the production process, and the temperature is too high, which can easily cause product deformation or direct and rapid burning. The production of grate bars adopts the traditional casting high-energy consumption process.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a split-type heat-insulating energy-saving grate bar, comprising a connecting surface body, a non-working surface body is fixedly connected to the top of the connecting surface body, the top of the non-working surface body is a heat insulation layer, a surface body groove is opened above the non-working surface body, the inside of the surface body groove is movably connected with a surface body protrusion block, one end of the surface body protrusion block is fixedly installed with an upper working surface, the upper part of the heat insulation layer is the upper working surface, and a countersunk bolt is also provided. The upper working surface, the heat insulation layer, and the non-working surface body are successively penetrated and connected together by countersunk bolts. After the connection, the top of the countersunk bolt is in the upper working surface and is not exposed. A high-temperature resistant and corrosion-resistant protective layer is attached to the top of the upper working surface, and a fastening bolt is penetrated at the bottom of the non-working surface body, and one end of the fastening bolt is movably connected with a thickened gasket.
[0007] Preferably, the thermal insulation layer is threadedly connected to the non-working surface body, and the countersunk bolts are distributed at equal intervals on the non-working surface body.
[0008] Preferably, guide ribs are fixedly provided above the connecting surface body and between the non-working surface body.
[0009] Preferably, a thermal insulation protective layer is bonded to the surface of the thermal insulation layer, the thermal insulation layers are tightly bonded to each other, and the thermal insulation protective layer is made of nano-ceramics.
[0010] Preferably, the surface body protrusion block fixedly installed at the bottom of the upper working surface is snap-connected with the surface body groove opened above the non-working surface body, and the surface body groove and the surface body protrusion block are used in conjunction with each other.
[0011] Preferably, the thickened gasket is threadedly connected to the non-working surface body, and the thickened gasket is symmetrically arranged with respect to the central axis of the non-working surface body.
[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0013] By connecting the surface body, guide ribs, non-working surface body, heat insulation layer, heat insulation protective layer, surface body groove, surface body protrusion block and upper working surface, when the split-type heat-insulating energy-saving grate is used, the upper working surface itself is made of high-quality material with high-temperature resistant and corrosion-resistant protective layer, so that the upper working surface of the split-type heat-insulating energy-saving grate has good high-temperature resistance and corrosion resistance when working, and the overall service life is increased.

Then, after the split-type heat-insulating energy-saving grate bar reaches its service life, it can continue to be used by simply removing the heat-insulating layer through countersunk bolts and replacing the upper working surface to reduce the cost of use. Finally, the production process of the split-type heat-insulating energy-saving grate bar is simple and does not use high-energy-consuming casting processes, saving energy and reducing carbon emissions. This combination of use not only improves the production efficiency of the split-type heat-insulating energy-saving grate bar, but also expands the overall scope of application and makes it more convenient to use in work;

At the same time, the connecting surface body and the guide ribs below the non-working surface body are connected by bolts and then welded to enhance the integrated use degree of the non-working surface body, making the split-type heat-insulating energy-saving grate more convenient to use in work.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] The utility model provides Figure 1-4 The split-type heat-insulating energy-saving grate shown includes a connecting surface body 1, a non-working surface body 3 is fixedly connected to the top of the connecting surface body 1, a heat-insulating layer 5 is located above the non-working surface body 3, a surface body groove 7 is provided above the non-working surface body 3, a surface body protrusion block 8 is movably connected inside the surface body groove 7, an upper working surface 9 is fixedly installed at one end of the surface body protrusion block 8, the upper working surface 9 is located above the heat-insulating layer 5, and a countersunk bolt 4 is also provided. The upper working surface 9, the heat-insulating layer 5, and the non-working surface body 3 are successively penetrated and connected together by the countersunk bolts 4. After the connection, the top end of the countersunk bolt 4 is located in the upper working surface 9 and is not exposed. A high-temperature resistant and corrosion-resistant protective layer 10 is attached to the top of the upper working surface 9, a fastening bolt 11 is penetrated at the bottom of the non-working surface body 3, and a thickened gasket 12 is movably connected to one end of the fastening bolt 11.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the thermal insulation layer 5 is threadedly connected to the non-working surface body 3, and the countersunk bolts 4 are evenly spaced on the non-working surface body 3. The countersunk bolts 4 strengthen the stability of the connection between the thermal insulation layer 5 and the non-working surface body 3, and improve the ability of the device to be used in an integrated manner. A guide rib 2 is also fixedly arranged above the connecting surface body 1 and between the non-working surface body 3. The overall structure of the guide rib 2 is simple and not only convenient for production, but also convenient for maintenance in case of failure. A thermal insulation protective layer 6 is bonded to the surface of the thermal insulation layer 5, and the thermal insulation layer 5 and the thermal insulation protective layer 6 are tightly fitted. The material of the thermal insulation protective layer 6 is: nano-ceramic. The thermal insulation protective layer 6 strengthens the thermal insulation capacity of the thermal insulation layer 5 and reduces unnecessary losses caused by the high temperature transferred to the non-working surface body 3 during production.
[0025] like Figure 1 , Figure 3 and Figure 4As shown, the surface body protrusion block 8 fixedly installed at the bottom of the upper working surface 9 is snap-connected with the surface body groove 7 opened above the non-working surface body 3, and the surface body groove 7 and the surface body protrusion block 8 are used in conjunction with each other.

The thickened gasket 12 is threadedly connected to the non-working surface body 3, and the thickened gasket 12 is symmetrically arranged with the central axis of the non-working surface body 3. If the thickness of the non-working surface body 3 of the split-type heat-insulating energy-saving grate is not enough, the thickened gasket 12 can be fixedly installed on the back of the non-working surface body 3 by tightening bolts 11 and welding, so as to adapt to the use requirements of grate bars of different sizes.
[0026] The working principle of the utility model is as follows: before the split-type heat-insulating energy-saving grate is produced, the raw materials are first purchased from the market, and the product is divided into four sections for production and processing. Each section is cut out by laser, and then the connecting surface body 1 and the guide rib 2 under the non-working surface body 3 are connected by bolts and then welded to complete the production of the non-working surface body 3, thereby enhancing the degree of integrated use of the non-working surface body 3. Then, after the production of the non-working surface body 3 is completed, the heat insulation layer 5 is connected to the non-working surface body 3 by countersunk bolts 4 through the threaded holes provided on the heat insulation layer 5. Then, the upper working surface 9 is embedded in the non-working surface body 3 through the surface body groove 7 set on the non-working surface body 3 and the surface body protrusion block 8 set at the bottom of the upper working surface 9. Then, the area of the heat insulation layer 5 is smaller than the upper working surface 9 and the non-working surface body 3. After the upper working surface 9, the non-working surface body 3 and the heat insulation layer 5 are fixed by threads, it is only necessary to weld the upper working surface 9 to the non-working surface body 3 by welding to complete the production of the split-type heat-insulating energy-saving grate. In this way, the entire production process is simple and does not use high-energy-consuming casting processes, reducing carbon emissions. When the split-type heat-insulating energy-saving grate is carried out If the thickness is not enough before use, the thickened gasket 12 can be fixedly installed on the back of the non-working surface body 3 by tightening the bolts 11 and welding, so as to adapt to the use requirements of grates of different sizes. Then, when using it, the upper working surface 9 itself is made of high-quality material with high-temperature resistant and corrosion-resistant protective layer 10, so that the upper working surface 9 of the split-type heat-insulating and energy-saving grate has good high-temperature resistance and corrosion resistance during work, and increases the overall service life. Then, the overall structure of the split-type heat-insulating and energy-saving grate is simple and acts on the equipment during operation, which can reduce downtime for maintenance. The number of times and maintenance time are reduced to increase production and reduce the workload of staff who replace the grate bars. After that, when the split-type thermal insulation and energy-saving grate bar reaches the end of its service life, it only needs to remove the thermal insulation layer 5 through the countersunk bolts 4 and replace the upper working surface 9 to continue to use it to reduce the cost of use. Finally, after completing the production and use of all the split-type thermal insulation and energy-saving grate bars according to the above operations, daily maintenance is sufficient. The material of the thermal insulation protective layer 6 is: nano-ceramic, and the material of the high-temperature resistant and corrosion-resistant protective layer 10 is: silicon carbide. In this way, the use process of the split-type thermal insulation and energy-saving grate bar is completed.
